ABSTRACT:
In a row-backlight column-shutter display, an array of sequentially illuminated leaky lightguides is utilized as the row-backlight component of the display. Light is coupled into each guide from a small high-peak-brightness source such as a light-emitting diode. Each guide is designed to leak light in a substantially uniform manner along the entire extent of a longitudinally extending edge of the guide. By combining such a row back light with an orthogonally disposed column shutter such as an array of ferroelectric liquid crystals, an advantageous flat panel display is realized.
